Graphene is a gapless semiconductor. As graphene is covered with one layer
of hydrogen or fluorine, it becomes a wide band gap insulator. However,
vacancies are easily found during the hydrogenated or fluorinated processes.
We investigate the electronic structure and magnetism of the hydrogenated
and fluorinated graphene with a variety of configuration of vacancies. We
found that a continuous zigzag chain distribution of vacancies will result
linear energy dispersion both in the hydrogenated and fluorinated graphene.
This finding should be very useful for the design of graphene based
electronic devices.
